T 0 all whom it may concern:

Be it known that 1, CHARLES Vi'on'rn- INGTON, a citizen of the United States, residing at Dunniield, Warren county, New Jersey, whose post-office address is the "same,

have invented certain new and useful Improvements in Cooling Systems for Internal- Combustion Engines, of which the following is a full, clear, and concise specification.

The invention relates to cooling ystems for the internal combustion engines 'of selfimpelled vehicles, and consists in means for maintaining an air current upon the parts to be cooled when the vehicle is slowed down or at rest, as hereinafter described and more particularly pointed out in the claims.

. In the accompanying drawing, Figure 1 represents one form of the invention applied v to a self-impelled vehicle of the kind wherein the engines are carried forward of the mainbody. of the car, certain of the parts being i shown in vertical longitudinal section; and

the body 2, the en parts are'carried on The "exhaust gases 3 are led-through a suitable conduit or conduits 4, 4, into a pipe or air passage 5, and the discharging ends of the said exhaust conduit or conduits, which may be provided with attached nozzles 6, as indicated, are arranged so as to expel the gases toward the outlet of said air passage in the rear of the vehicle. The pipe or air passage 5 is suitably supported or hung from any convenient part of the vehicle, and is preferably disposed as compactly and inconspicuously as possible beneath the car body. At its forward end it merges into an enlarged, forwardly opening chamber of hood, marked 7, which serves to collect and conduct air into and through the air passage when the vehicle is in motion. The radiator 8 or such part or parts of the propelling mechanism as require to be cooled are disposed in the path of the air current entering the hood and the pas sage 5. As shown in the drawing, the radiator 8 is (placed in front of the hood. It is connecte by the usual circulation pipes 9,

with the water jackets ofthe engines, which latter are of the internal combustion type.

1 gases within the air passage, by its inductive i action, supplements the current produced by l the motion of the vehicle, and at such times '1 as when the vehicle is slowed down or sta tionary, but with the engine still running, it so that the cooling of the radiator or the engine is continued independently of the mo- 1 tion of the vehicle. The inductive effect of l the exhaust discharge is increased, according to this invention, by providing the conduit or conduits 4, 4 with means for varying the size of their discharge openings, which means will ordinarily be operated to restrict the opening when the vehicle is slowed downor stationary, and by thus increasing the vemaintains an air current in the air passage,

locity of discharge, will also increase the velocity of the air current induced in the passage and hence will maintain the cooling ac-- The variablerestricting means may con- I s ist of a plug or plugs 13 carried on a slide rod 10 longitudinally mounted within the air passage 5, so as to be movable, more or less,

into the discharging orifices of the nozzles 6.

The slide rod may be operated in an desired manner,-but the invention contemp ates the employment of the usual clutch pedal for this purpose so that when the clutch is thrown out the exhaust will be simultaneously restricted and the induced air current corre spondingly and immediately increased. The operating connections 'for this purpose inc ude a crank shaft 14 for operating the slide clutch rod 16 of pedal 17.

I claim:

'1. In a self-impelled vehicle, the combination of an air part to be coo ed, an internal combustion engine having its exhaust pipe disposed within said passage for inducing an air current therethrough and means for variably restricting the discharge from said exhaust pipe to increase its inductive efiect. l 2. In a cooling system for self-impelle vehicles, an air'passage, a part therein to be cooled, an internal combustion engine for impelling the vehicle, having its exhaust pipe disposed within said passa e to induce a current of air therein, and a su stantially conical plug movably mounted in the orifice of said rod 10 and link connections 15 with the assage containing therein a discharge conduit whereby the induction in the passage is increased when the exhaust is throttled.

3. The combination in a self-impelled Vehicle, of an internal combustion engine, having an exhaust pipe and a throttle for said pipe, a clutch for transmitting the motion of the engine to the vehicle wheels, and means for releasing said clutch having a connection 5 with said throttle for simultaneously restricting the discharge from said exhaust pipe.

4. In a self-impelled vehicle, an air pas- I sage containing therein a part to be cooled, 1

an internal combustion engine for driving the vehicle having its exhaust pipe dispose to induce an aircurrent within said passage, and a throttle for said pipe adapted to restrict the discharge within said combination with a clutch in the rivlng connections between the engine and vehicle adapted simultaneously throttle to restrict the discharge.

In testimony whereof, I have signed my l name to the specification in the presence of two subscribing witnesses. CHARLES C. \VORTHINGTON.
